[0002] Currently, 3D display technology is widely used in entertainment, healthcare, and education, providing users with an immersive visual experience through stereoscopic imaging. However, traditional 3D display technologies often use opaque or low-transparency display panels, limiting their application in certain specific scenarios (such as augmented reality and transparent display devices). In recent years, with the development of augmented reality (AR) and mixed reality (MR) technologies, the demand for semi-transparent 3D display structures has been increasing, but existing technologies still face the challenge of balancing transparency and display quality.

[0003] The main technical means to achieve semi-transparent 3D display at present include: (1) using a polarized beam splitter combined with a transparent OLED screen to achieve a semi-transparent effect by splitting the light, but there are problems of brightness loss and limited viewing angle; (2) using holographic projection technology to generate 3D images by using interference and diffraction principles, but the equipment is complex and the cost is high; although these technologies can partially achieve semi-transparent 3D display, they still face many challenges in practical applications.

[0004] Therefore, how to provide a semi-transparent 3D display structure that combines high transparency and excellent display effect, while reducing manufacturing costs and improving user experience, is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a semi-transparent 3D display structure, which adopts the following solution:

[0006] A semi-transparent 3D display structure includes: a main frame; a transparent protective component embedded within the main frame, wherein a first embedding groove is provided within the main frame corresponding to the transparent protective component; a liquid crystal display module, including a liquid crystal display screen and a mounting bracket, wherein the liquid crystal display screen is fixed to the main frame by the mounting bracket and embedded in the main frame, wherein a second embedding groove is provided within the main frame corresponding to the liquid crystal display module; a backlight panel embedded within the main frame and located at the end of the liquid crystal display module away from the transparent protective component, wherein a third embedding groove is provided within the main frame corresponding to the backlight panel; and a left side panel mechanism, including a transparent cover plate assembly and a lamp plate, wherein the transparent cover plate assembly covers the lamp plate and is snapped onto the side of the main frame, and a first group of LED beads is provided on the side of the lamp plate away from the transparent cover plate assembly for illuminating the liquid crystal display screen.

[0007] By adopting the above technical solution, the main frame can support and fix the transparent protective component, the liquid crystal display module, the backlight panel, and the left side panel mechanism. The transparent protective component is embedded in the first recess of the main frame, which can prevent the liquid crystal display module and other components from being affected by external collisions, dust, etc., and protect the internal structure.

[0011] By adopting the above technical solution, the left panel is fitted with a neon transparent piece and bonded together by ultrasonic bonding to form a transparent cover plate assembly. This can improve the stability of the connection between the two, ensure the overall structural stability of the transparent cover plate assembly, and thus ensure the normal use of the left panel mechanism, providing support for the stable operation of the semi-transparent 3D display structure.

[0012] Optionally, the left side panel is provided with a first tooth and a first engaging component, the main frame is provided with a first tooth groove corresponding to the first tooth, and a first fastening component is provided corresponding to the first engaging component. The neon transparent component is sleeved on the left side panel and inserted into the first tooth groove through the first tooth.

[0013] By adopting the above technical solution, the main frame engages with the first tooth of the left side panel through the first tooth groove, and the first fastener engages with the first snap-fit ​​of the left side panel, thus fixing the neon transparent piece of the left side panel onto the main frame. This ensures the stable installation of the left side panel mechanism and guarantees the overall stability of the semi-transparent 3D display structure. Simultaneously, this structure facilitates assembly and disassembly, making subsequent maintenance and repair convenient. Furthermore, this structure ensures a tight connection between the transparent cover assembly and the main frame, helping to improve the sealing and protection of the display structure.

[0014] Optionally, it also includes: a right-side panel mechanism, disposed on the main frame away from the left-side panel mechanism, and the right-side panel mechanism includes: a main control board, disposed on one side of the main frame and electrically connected to the LCD screen and the light panel; a right-side panel, covering the main control board and snapped onto the side of the main frame; a decorative piece, fixed to the side of the right-side panel away from the main control board; and a control component, penetrating the decorative piece and the right-side panel and connecting to the main control board.

[0015] By adopting the above technical solutions, the main control board enables unified control and management of the LCD screen and the light panel, making the operation of the semi-transparent 3D display structure more orderly and stable. The right panel is snapped onto the side of the main frame and covers the main control board, which not only protects the main control board from external environmental influences but also facilitates installation and disassembly, making it easier for later maintenance. The decorative parts fixed on the right panel can beautify the appearance and enhance the visual effect of the product. The control components pass through the decorative parts and connect to the main control board through the right panel, making it convenient for users to operate and control the entire display structure.

[0016] Optionally, the right-side panel mechanism includes: a pressing condition disposed on the side of the main frame for abutting against the transparent protective component, the fixing frame, and the backlight panel, wherein the main control board is fixed on the pressing condition; wherein, during assembly, the transparent protective component, the liquid crystal display module, and the backlight panel are inserted from the side of the main frame that fixes the pressing condition.

[0017] By adopting the above technical solution, the pressure condition abutting against the transparent protective component, the fixing frame and the backlight panel can play a stable supporting role, and fixing the main control board on the pressure condition facilitates reasonable layout and installation; allowing the transparent protective component, the LCD display module and the backlight panel to be inserted from the side of the main frame that fixes the pressure condition makes the assembly process simpler and improves assembly efficiency.

[0018] Optionally, the right side panel is provided with a second tooth and a second engaging member, the main frame is provided with a second tooth groove corresponding to the second tooth, and a second fastening member is provided corresponding to the second engaging member. The right side panel is inserted into the second tooth groove through the second tooth, and the second engaging member is fastened into the second fastening member and fixed on the main frame.

[0019] By adopting the above technical solution, the semi-transparent 3D display structure includes a main frame, transparent protective components, a liquid crystal display module, a backlight panel, and a left side panel mechanism, realizing basic semi-transparent 3D display functions; the light guide and neon lights in the left side panel mechanism can create special lighting effects; the transparent cover plate assembly is integrally molded to ensure integrity; at the same time, the right side panel can be firmly fixed to the main frame by inserting the second tooth into the second tooth groove and the second snap-fitting component into the second snap-fitting component, which facilitates assembly and ensures the stability of the right side panel installation.

[0020] Optionally, the distance between the transparent protective component and the liquid crystal display screen is set to 3-6 mm; the distance between the liquid crystal display screen and the backlight panel is set to 8-15 mm.

[0021] By adopting the above technical solutions, setting the distance between the transparent protective component and the LCD screen to 3-6 mm can protect the LCD screen while ensuring good visual effects; setting the distance between the LCD screen and the backlight panel to 8-15 mm allows the backlight to be evenly distributed on the LCD screen, improving display quality. Simultaneously, the distance setting can utilize the spatial parallax effect to enhance dynamic depth performance, inducing continuous spatial depth perception in a two-dimensional display interface, achieving an enhanced visual presentation with stereoscopic depth cues.

[0033] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0035] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0036] See Figure 1 , Figure 2 and Figure 3 The present application discloses a semi-transparent 3D display structure, including a main frame 10, a transparent protective component 20, a liquid crystal display module 30, a backlight panel 40, and a left side panel mechanism 50. The transparent protective component 20, the liquid crystal display module 30, and the backlight panel 40 are sequentially embedded in the main frame 10, and the left side panel mechanism 50 is snapped onto the side of the main frame 10 to form an integrated display structure, ensuring the stability of the display structure and achieving a semi-transparent 3D display effect.

[0037] Specifically, the main frame 10 serves as the supporting foundation for the entire display structure, providing mounting and fixing positions for other components. The main frame 10 is made of high-strength, lightweight materials, such as aluminum alloy or engineering plastics. Inside the main frame 10, different embedding slots are provided for different components, namely the first embedding slot 11, the second embedding slot 12, and the third embedding slot 13. The shape and size of each embedding slot are matched with the corresponding component to ensure that each component can be accurately embedded within it.

[0038] The transparent protective component 20 is embedded in the first embedding groove 11 of the main frame 10. The transparent protective component 20 is made of transparent glass or transparent plastic. Transparent glass has the characteristics of high transparency, high hardness, and good wear resistance, which can effectively protect internal components from external physical damage; while transparent plastic has the advantages of light weight and strong impact resistance. The transparent protective component 20 plays a role in protecting the internal display components, preventing dust, moisture, etc. from entering, while ensuring that light can pass through smoothly and maintaining the transparency of the display structure.

[0039] See Figure 2 and Figure 3 The liquid crystal display module 30 includes a liquid crystal display screen 31 and a mounting bracket 32. The liquid crystal display screen 31 is the core component for image display, capable of presenting clear and realistic images. The mounting bracket 32 ​​is used to fix the liquid crystal display screen 31 and is typically made of metal or plastic. A metal mounting bracket 32 ​​has high strength and stability, firmly securing the liquid crystal display screen 31; a plastic mounting bracket 32 ​​is lightweight and low-cost. After being fixed by the mounting bracket 32, the liquid crystal display screen 31 is embedded in the second embedding slot 12 of the main frame 10. This design ensures that the liquid crystal display screen 31 is stably installed, not easily shaken, and guarantees the stability of the display effect.

[0040] The backlight panel 40 is an optical-grade acrylic backlight panel, embedded in the third embedding slot 13 of the main frame 10, and located at the end of the liquid crystal display module 30 away from the transparent protective member 20. The backlight panel 40 provides a backlight source for the liquid crystal display screen 31, enabling it to display images normally. The backlight panel 40 typically uses LED lights as its light source, which have advantages such as energy saving, long lifespan, and uniform light emission. The light emitted by the backlight panel 40 passes through the liquid crystal display screen 31 and then through the transparent protective member 20, forming the image we see.

[0041] In this embodiment, the distance between the transparent protective component 20 and the liquid crystal display screen 31 is set to 3-6 mm, and the distance between the liquid crystal display screen 31 and the backlight panel 40 is set to 8-15 mm. This allows the use of spatial parallax effect to enhance dynamic depth performance, induce continuous spatial depth perception in the two-dimensional display interface, and achieve an enhanced visual presentation with stereoscopic depth cues.

[0042] See Figure 3 and Figure 4 The left panel mechanism 50 includes a transparent cover assembly 51 and a light panel 52. The transparent cover assembly 51 covers the light panel 52 and is snapped onto the side of the main frame 10. The transparent cover assembly 51 serves to protect the light panel 52 and allow light to pass through, and is made of transparent material, such as transparent plastic or transparent glass. A first LED bead group 521 is provided on the side of the light panel 52 away from the transparent cover assembly 51 (see...). Figure 5 The light emitted by these LEDs is used to illuminate the LCD screen 31, enhancing the brightness and contrast of the LCD screen 31, thereby improving the display effect.

[0043] Furthermore, the left panel mechanism 50 also includes a light guide 53, which is covered by a transparent cover assembly 51 and located between the transparent cover assembly 51 and the light panel 52. A neon light 531 is provided on the side of the light guide 53 away from the light panel 52, and a second LED group 522 is provided on the side of the light panel 52 close to the light guide 53. The second LED group 522 illuminates the neon light 531 through the light guide 53 and transmits light through the transparent cover assembly 51.

[0044] The light guide 53 is configured as a combination of a 2mm ultra-thin light guide plate and a quantum dot enhancement film. A microprism structure is fabricated on the bottom surface of the light guide plate using nanoimprinting technology to reduce the thickness of the light guide 53 while maintaining light efficiency. The light guide 53 is fixed to the main frame 10 with screws. The function of the light guide 53 is to uniformly guide the light emitted by the second LED group 522 onto the neon light 531. The neon light 531 can emit various colors of light to enhance the visual effect and aesthetics of the display structure.

[0045] The transparent cover assembly 51 still serves to protect the internal components and allow light to pass through. When the second LED group 522 is lit, the light is transmitted to the neon light 531 through the light guide 53. The neon light 531 emits colorful light, which then shines out through the transparent cover assembly 51, making the entire display structure more beautiful and unique.

[0046] The transparent cover assembly 51 includes a left side panel 511 and a neon transparent element 512. The neon transparent element 512 is fitted onto the left side panel 511 and bonded together using ultrasonic bonding. The left side panel 511 is generally made of plastic or metal, possessing a certain strength and rigidity to protect the neon transparent element 512. The neon transparent element 512 is made of transparent plastic or glass, allowing light to pass through and displaying the color effect of neon lights 531.

[0047] Specifically, the left side panel 511 is provided with a first tooth 5111 and a first engaging member 5112. The main frame 10 is provided with a first tooth groove 14 corresponding to the first tooth 5111, and a first fastening member 15 corresponding to the first engaging member 5112. The neon transparent member 512, fitted onto the left side panel 511, is inserted into the first tooth groove 14 through the first tooth 5111, and the first engaging member 5112 is fastened into the first fastening member 15 to fix it to the main frame 10. This snap-fit ​​and fastening method allows the left side panel 511 to be firmly fixed to the main frame 10, ensuring the stability of the structure.

[0048] Further, see Figure 1 and Figure 4 In this embodiment, a right-side panel mechanism 60 is also included, which is located on the side of the main frame 10 away from the left-side panel mechanism 50, and includes a main control board 61, a right-side panel 62, a decorative piece 63, and a control component 64.

[0049] The main control board 61 is located on one side of the main frame 10 and is electrically connected to the LCD screen 31 and the backlight board 52. The main control board 61 is the control center of the entire display structure; it is responsible for receiving external signals and controlling the LCD screen 31 and the backlight board 52, adjusting display parameters and backlight brightness, etc. The main control board 61 typically uses high-performance microprocessors and circuit components to ensure stable control performance.

[0050] See Figure 4 and Figure 5The right-side panel 62 covers the main control board 61 and is snapped into place on the side of the main frame 10. The right-side panel 62 protects the main control board 61 and also enhances the appearance of the entire display structure. The right-side panel 62 has a second tooth 621 and a second engaging member 622. The main frame 10 has a second groove (not shown in the figure) corresponding to the second tooth 621, and a second fastening member 16 corresponding to the second engaging member 622. The right-side panel 62 is inserted into the second groove via the second tooth 621, and the second engaging member 622 is fastened into the second fastening member 16, securing it to the main frame 10. It should be noted that the snap-fit ​​method of the right-side panel 62 is the same as the fixing method of the left-side panel 511, ensuring a secure installation of the right-side panel 62.

[0051] Decorative component 63 is fixed to the side of the right panel 62 away from the main control board 61. It can be in various shapes and colors to beautify the display structure. Control component 64 passes through decorative component 63 and right panel 62 and connects to main control board 61. Users can operate the display structure through control component 64, such as turning it on and off, adjusting brightness, etc.

[0052] See Figure 5 The right panel mechanism 60 also includes a pressing condition 65, which is set on the side of the main frame 10 and is used to abut against the transparent protective component 20, the fixing frame 32 and the backlight panel 40, wherein the main control board 61 is fixed on the pressing condition 65.

[0053] During assembly, the transparent protective component 20, the liquid crystal display module 30, and the backlight panel 40 are inserted from the side of the main frame 10 through the fixing pressure condition 65, and then fixed to the main frame 10 by the pressure condition 65, so as to achieve the abutment and fixation of the transparent protective component 20, the fixing bracket 32, and the backlight panel 40. This assembly method is simple and convenient and can improve production efficiency.

[0054] The implementation principle of this embodiment is as follows: the main frame 10 organically combines various components to form a complete display system; the transparent protective component 20 protects the internal components while ensuring the transparency of the structure; the liquid crystal display module 30 is responsible for displaying images; the backlight panel 40 provides the necessary backlight source; the first LED group 521 on the lamp plate 52 in the left panel mechanism 50 can enhance the display effect of the liquid crystal display screen 31; the setting of the second LED group 522, the light guide 53 and the neon light 531 on the lamp plate 52 can realize that the light guide 53 can effectively guide the light of the second LED group 522 to the neon light 531, thereby realizing the rational utilization and transmission of light; by connecting the left panel 511 and the neon transparent component... The ultrasonic bonding of the 512 components enhances the integrity and stability of the transparent cover assembly 51. The first tooth 5111 and the first engaging component 5112, in conjunction with the first tooth groove 14 and the first fastening component 15 of the main frame 10, reliably fix the left panel 511. Similarly, the second tooth 621 and the second engaging component 622, in conjunction with the second tooth groove and the second fastening component 16 of the main frame 10, reliably fix the right panel 62. During assembly, the transparent protective component 20, the liquid crystal display module 30, and the backlight panel 40 are inserted from the side of the fixing pressure condition 65 of the main frame 10 and then fixed using the pressure condition 65. This assembly method is simple and convenient, improving production efficiency.
